I went to an all girls school and am really grateful. The pressure of who's going out with who, who fancies who,who has a boyfriend, the disruptions that boys can cause in class, the change of behaviour and attitude from girls when boys are around, would have taken me away from caring about my education and caused me alot of angst. Not to mention going through puberty with boys around- the teasing about growing breasts etc. It's hard enough being a teenage girl as it is. Of course I was pretty nervous around boys when I got to sixth form but I soon got over that.
